1.

wheel nuts (2 points at least).
2.
Check the wheel bearing axial end play before the inspection.
Refer to
3.
Inspect the runout with a dial indicator to measure at 10 mm
(0.39 in) inside disc edge.
4.
Find the installation position that has a minimum runout by shifting the disc rotor-to-wheel hub and bearing
assembly installation position by one hole at a time if the runout exceeds the limit value.
5.
Refinish the disc rotor if the runout is outside the limit even after performing the above operation. [When
refinishing, use the Pro-Cut PEM On-Car brake Lathe (Tool No. 38-PFM90.5) or equivalent.]
CAUTION:
• Check in advance that the thickness of the disc rotor is wear thickness + 0.3 mm (0.012 in) or
more.
• If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc rotor.
Thickness
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the wear limit.
ADJUSTMENT
CAUTION:
• Burnish contact surfaces between disc rotors and pads according to the following procedure after
refinishing or replacing disc rotor, or if a soft pedal occurs at very low mileage.
• Be careful of vehicle speed because the brake does not operate firmly/securely until pad and disc
rotor are securely fitted.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1.
Drive vehicle on straight, flat road.
2.
Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3.
Drive without depressing brake for a few minutes to cool the brake.
4.
Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
